Budget RCA/Power Plugs for DIY

Long story short, my system is finally getting to the point where I can hear micro-details in the music reproduction. I'm able to hear the differences in cables and even the RCA plugs on my interconnects...a year ago I would have been skeptical about such differences, but my current system is resolving that well!

I have my wire picked out, it's a nice silver plated copper. I'm looking for some quality RCA plugs that *are not* $100+ a pair. I'm not married to any brand or style, and I can solder and finish cables quite well, just looking for good bang for the buck plugs. Currently I'm taking the RCA plugs off 20 year old Monster M350 cable and reusing them - I'm sure most anything aftermarket would be better.

Also, I'm going to try my hand at making myself a power cord - just out of curiosity, to see if I can hear a difference. I've already got a dedicated ground, 20 amp circuit to my tube amp with a basic Hubble Hospital Grade Outlet, and a fresh 100amp circuit to the house for my listening room. What decent but budget IEC and Plug would you recommend I look at? Again, I don't want to spend over $100 for these two plugs.

I'm looking forward to your suggestions!
